The French Riviera is home to the beach resorts of Saint Tropez and Cannes, but it has also been host to some of the world’s greatest artists. In 1946, Pablo Picasso left Paris for Antibes, where he worked for three months in the Grimaldi Chateau; and in 1949, Chagall bought a house in the French commune of Vence, and proceeded to interact with the region by creating public art, including a mosaic for a local cathedral. The “Monaco Masters Show” looks at the ways Picasso, Chagall, Fernand Léger, Alexander Calder, and others were influenced by the French Riviera, or rather “La Côte d’Azur.” It wasn’t all sunshine, though. In 1953, Niki de Saint Phalle’s time in Nice was interrupted by treatment in a mental clinic; and in 1955, in Antibes, the abstract painter Nicolas de Staël, suffering depression, took his own life. —Zack Hauptman
